The White House says it will refuse all Congressional subpoenas for documents or testimony because they're all unnecessary. It is unnecessary for the legislative branch to investigate the executive branch because the executive branch has already investigated the executive branch.

How long before Trump declares that Congress is unnecessary because he can declare the laws by executive order, and that the Judicial branch is unnecessary because he himself can determine who has broken which laws. Doing away with Congress and the judiciary will remove the present obstacles that legislators and judges are using to keep him, Trump, from making America great again. And it will be much more efficient and save taxpayers huge amounts of money. So, let's get on with it. Kneel before the King and America will be great again.
